We’ve featured plenty of news lately about updates to laptops but here’s news for Mac-lovers who like their computers to "stay at home". Apple has unveiled an all-new iMac range featuring bigger and brighter LED-backlit 21.5 and 27-inch widescreen displays in a new edge-to-edge glass design and seamless all-aluminum enclosure. Apple says the new models are the fastest iMac’s ever, with Intel Core 2 Duo processors starting at 3.06GHz, and Core i5 and i7 quad-core processors for extra performance. What’s more, new iMacs come with a wireless keyboard and the all-new wireless Magic Mouse, the world’s first mouse with Multi-Touch technology pioneered by Apple on the iPhone.

The new iMacs feature LED-backlit displays with a 16:9 aspect ratio that makes improves the experience of watching high definition movies and TV shows from iTunes, and editing and watching your own videos or photos using iLife even easier.

The 27-inch iMac features a whopping 2560 x 1440 pixel display that provides 60 percent more pixels than the previous 24-inch model. The new 21.5-inch iMac has a high resolution 1920 x 1080 pixel display. Both the 21.5 and 27-inch displays use IPS technology to deliver consistent color across an ultra wide 178° viewing angle.

The iMac comes standard with a wireless keyboard and the impressive new Magic Mouse featuring Apple’s revolutionary Multi-Touch technology. No buttons, scroll wheels or scroll balls on this device because the entire top of the Magic Mouse is a seamless Multi-Touch surface that lets users navigate using familiar finger gestures. The wireless keyboard and Magic Mouse work seamlessly with the iMac’s built-in Bluetooth capabilities to provide a cable-free desktop.

Memory can be ramped up from 4GB of 1066MHz DDR3 to 16GB across four SO-DIMM slots and every iMac features a built-in iSight video camera, mic and stereo speakers integrated into the thin aluminum and glass design.

Apple today also announced that the Mac mini, what it claims is the world’s most energy efficient desktop, is now faster, offers more storage and comes standard with double the memory.
